SEALING DEVICE OF HIGHER RELIABILITY Russian patent published in 2010 - IPC E05B39/02 

FIELD: construction.

SUBSTANCE: invention is related to devices for locking and simultaneous sealing of rail cars, vans. Invention objective is development of reliable, simple and manufacturable sealing device, having high resistance to criminal unsealing. Device is proposed, which comprises a section of rope undetachably fixed by passive end in body, mechanism of fixation installed in internal cavity of body. Body, rolled cover closing cavity of body on the side of its outlet hole and separator have holes for rope. Body is arranged with cylindrical shape with internal stepped cavity formed by conical surface coupled with cylindrical surface on the cover side. In body, on both sides, there are protective bushes arranged with the possibility of axial rotation, and profile of their holes follows profile of rope cross section, and on internal surface of bush there are helical grooves arranged with pitch that equals pitch of rope strands layer. Separator is made of two parts, one of which has a shape of truncated cone, and the second one - shape of coupled cylinder arranged in the form of bush, in internal part of which there is a compression spring installed, which interacts with rolled cover. Length of separator bush is selected so that as rope is pulled through body, bottom of separator bush contacts cover. In conical part of separator there are two seats arranged with a roller in each of them. Length of seat slot is more or equal to 1.5 of roller diametres. In body, on the side of inlet hole, at the right angle to axial hole, but in different planes with it, there is hole provided for rope insertion, and bulges formed by die in process of rope clamping are arranged in end surface of body near its inlet hole.

EFFECT: provision of sufficient protection against criminal unsealing.
